Hodgson (1967), Chapter 4, reports that Alec Barnes discovered Shambar in 1936 as a Marsh limb sport in Corona. Later accounts disagree about the reported sport parent; this credit records the attributed discovery, not resolution of that disagreement.
UCR’s CRC 3831 profile and Hodgson (1967) report that Alec Barnes discovered Shambar in 1936 as a Marsh limb sport in Corona. Da Graça et al. (2004) also identify Marsh in the article body, while the abstract identifies Thompson Pink. These sources conflict on the reported sport parent; the account does not resolve that identity.
